deliver electronic mail with scala from the future
Via the copy and paste method
resolvers += "softprops-maven" at "http://dl.bintray.com/content/softprops/maven"
libraryDependencies += "me.lessis" %% "courier" % "0.1.3"Via a more civilized method which will do the same without all the manual work.
> ls-install courier
Note. If you are a bintray-sbt user you can optionally specify the resolver as
resolvers += bintray.Opts.resolver.repo("softprops", "maven")deliver electronic mail via gmail
import courier._, Defaults._
val mailer = Mailer("smtp.gmail.com", 587)
.auth(true)
.as("you@gmail.com", "p@$$w3rd")
.startTtls(true)()
mailer(Envelope.from("you" `@` "gmail.com")
.to("mom" `@` "gmail.com")
.cc("dad" `@` "gmail.com")
.subject("miss you")
.content(Text("hi mom"))).onSuccess {
case _ => println("message delivered")
}
mailer(Envelope.from("you" `@` "work.com")
.to("boss" `@` "work.com")
.subject("tps report")
.content(Multipart()
.attach(new java.io.File("tps.xls"))
.html("<html><body><h1>IT'S IMPORTANT</h1></body></html>")))
.onSuccess {
case _ => println("delivered report")
}Since courier is based on JavaMail, you can use Mock JavaMail to execute your tests. Simply add the following to your build.sbt:
libraryDependencies += "org.jvnet.mock-javamail" % "mock-javamail" % "1.9" % "test"Having this in your test dependencies will automatically enable Mock JavaMail during tests. You can then test for email sends, etc.
import courier._
import org.specs2.mutable.Specification
import scala.concurrent.duration._
// Need NoTimeConversions to prevent conflict with scala.concurrent.duration._
class MailSpec extends Specification with NoTimeConversions {
"the mailer" should {
"send an email" in {
val mailer = Mailer("localhost", 25)
val future = mailer(Envelope.from("someone@example.com")
.to("mom@gmail.com")
.cc("dad@gmail.com")
.subject("miss you")
.content(Text("hi mom")))
Await.ready(future, 5.seconds)
val momsInbox = Mailbox.get("mom@gmail.com")
momsInbox.size === 1
val momsMsg = momsInbox.get(0)
momsMsg.getContent === "hi mom"
momsMsg.getSubject === "miss you"
}
}
}
} Here is an excellent article on using Mock JavaMail.
